Mangrove survives in the most hostile environment with
fluctuating tidal and saline regime. The present work focused on a detailed
study on quantitative estimation of phytoconstituents and DPPH radical
scavenging activity of Excoecaria agallocha L., a mangrove from Kattiparambu
and Chirackal of Ernakulam District, Kerala. Preliminary phytochemical
investigation indicated the presence of biologically active metabolites of
leaf, stem and root of the plant in different solvents. Methanol and hexane
gave maximum results. Since the plant grows in stress conditions showed the
presence of amino acids. Recorded values for high protein in leaf (4.8%), stem
(1.93%), Carbohydrate in the root (11.17%) at Chirackal. Phenols (6.02%),
flavanoids (3.6%) and tannins (5.68%) was observed in leaf samples of the
species at Chirackal. Methanolic extract showed maximum free radical scavenging
activity (IC50-141.56 µg/ml) in leaf samples and stem showed minimum
(IC50-931.3 µg/ml) in chloroform extract. The range of DPPH radical scavenging
activity in the solvent is Methanol > Ethyl acetate > Ethanol >
Chloroform.
